Ultrasonic cutting technology widely applied in lightweight structures: Nowadays, many industries take weight reduction as a driving force for innovation, primarily including automotive technology, aerospace technology, and medical technology. Ultrasonic cutting provides favorable prerequisites for the processing of materials that are increasingly being used in lightweight structures.
Nowadays, effective cutting of different materials can be achieved through replaceable blades, such as glass fiber or carbon fiber fabrics, foam materials, leather, artificial leather, rubber, thick cardboard, or paper.
The frequency of ultrasonic waves exceeds the audible threshold, generally above approximately 20 kHz. The frequencies used for cutting fall within the range of 20 kHz to 30 kHz. Ultrasonic waves are generated by a piezoelectric transducer that causes the blade to vibrate at a high frequency, delivering extremely powerful effects during resonance while requiring relatively low power. Therefore, when the thermal load on the environment is low, the cut slices are very neat. There is no need to worry about product adhesion on the blade. Additionally, this process offers other advantages, making it particularly suitable for cutting materials used in lightweight structures. Compared to mechanical milling, ultrasonic cutting does not result in any material loss. There is no debris; the cutting edges are smooth and clean, eliminating the need for finishing.
No cutting medium is required for operations such as water jet cutting. The cut materials remain dry and clean. The cutting depth can be adjusted arbitrarily. Moreover, ultrasonic cutting produces low noise levels, eliminating the need for any noise protection measures. Furthermore, unlike laser cutting, the surface of the cut materials does not fail to meet special quality assessment standards; there are no charred cutting edges or combustion gases. Due to its extremely low acquisition and operating costs compared to other processes, ultrasonic cutting has become a practical technology required for numerous lightweight structure applications.
